If you refer to https://docs.microsoft.com/en-us/microsoftteams/direct-routing-sbc-multiple-tenants

and under the section Register a Base Domain and subdomains. Their example has the carrier base domain as adatum.biz and then an additional domain customers.adatum.biz so my example follows Microsoft's logic.

No - you don't need to add PSTNOnlineGateway parameter to the customer tenant. That same document again. Search for Create a trunk and provision user. That gives some information there about derived trunks.

Hi fowler_23

I got all this working in the end but I didn't need to create subdomains as per the MS example and you do need to have the PSTN Gateway List populated when creating the carrier trunk. If you dont do this there is no way to tell the voice route where it should route to so I believe the MS document to be misleading. Their documentation states you need to use the FQDN of the SBC in the voice route but the command doesn't show this and you cannot add it in any other way apart from that parameter. I have reviewed other posts on this and found the same. I just thought I'd update this post and feedback my findings.

Thanks!
